No wash bucket is complete without the 5 Wheel Car Wash Dolly! The dolly accommodates any 3.5 – 7 gallon round bucket and has 5 heavy-duty casters capable of supporting up to 110 kg. The dolly makes your wash bucket mobile so you can easily roll it around a vehicle as you wash it. Each Dolly contains locking mechanisms on the castors that will prevent any chance of your buckets rolling away. These durable metal castors also glide easily over almost any surface and give the buckets unlimited maneuverability and shorten your wash times. Three thumb screws hold the bucket in place inside the dolly. This dolly works perfectly with Prime Finish 20 Litre Car Wash Buckets.
